Apparatus for mounting an open end spinning turbine

Abstract

Apparatus for mounting an open end spinning turbine positioned adjacent the front end of a drive shaft includes a bearing block which has a pair of spaced walls traversed by the drive shaft. Rollers are provided between the spaced walls forming a V-groove support for the drive shaft. The rear end of the shaft extends outwardly of the rear wall of the bearing block and has an annular T-slot formed therein. A bushing is mounted in the wall for journalling of the shaft, and a guide member extends within the T-slot for establishing the axial location of the shaft within the supporting rollers.

       4. The apparatus according to claim 3, wherein said roller is mounted eccentrically to its axis and is rotatably adjustable to vary the distance between it and said shaft. 
     
     
       5. The apparatus of claim 1, wherein said drive shaft has a larger diameter in that portion extending from said turbine to said annular T-slot than in that portion between said annular T-slot and the end thereof. 
     
     
       6. The apparatus of claim 1, wherein the engaging edges of said annular T-slot and said guide member are beveled. 
     
     
       7. The apparatus according to claim 1, including an adjustable buffer to limit movement of said guide member in the direction towards the shaft. 
     
     
       8. The apparatus according to claim 1, including an adjustable buffer to limit movement of said guide member in the direction away from the shaft. 
     
     
       9. The apparatus according to claim 1, including a housing mounted on the wall enclose at least said guide member. 
     
     
       10. The apparatus according to claim 1, including seal means for sealing said housing and a lubricant contained therein. 
     
     
       11. The apparatus according to claim 1, wherein said bushing and said guide member are fastened upon a movable support which enables the displacement relative to said drive shaft. 
     
     
       12. The apparatus of claim 11, wherein said support comprises a movable slide bar mounted in said housing. 
     
     
       13. The apparatus according to claim 11, wherein said support is movable to move said slide bar in a plane perpendicular to the axes of the V-groove roller means in a path comprising the tangent to the point of contact of said shaft and the V groove. 
     
     
       14. The apparatus according to claim 11, wherein said drive means comprises a tangential belt having means for lifting the belt from said shaft, said lift-off mmeans being arranged in the area of the V groove rollers at which said slide bar is tangentially displaceable. 
     
     
       15. The apparatus according to claim 11, wherein said bushing is disposed in an oblong slot in the wall, and said slide bar is provided with an oblong slot straddling a lug fastened to said wall, thereby defining said tangential movement. 
     
     
       16. The apparatus according to claim 13, wherein the guide member is axially adjustably journalled upon the lug. 
     
     
       17. The apparatus according to claim 13, including means for fixing said guide body on said lug relative to said shaft. 
     
     
       18. The apparatus according to claim 15, wherein said fixing means comprises a locknut mounted upon a thread-extension of the lug and a compression spring encircling the lug supported at its other end by a collar formed on said lug. 
     
     
       19. The apparatus according to claim 1, wherein said guide member is mounted on an arm journalled at one end to swing about an axle parallel to said shaft. 
     
     
       20. The apparatus according to claim 19, wherein said arm comprises a U-shaped bracket having near the ends of its free legs a bearing axle for said guide member. 
     
     
       21. The apparatus according to claim 19, including means for axially adjusting said arm along its swivel axle. 
     
     
       22. The apparatus according to claim 1, wherein said roller is journalled on an axle pivotally mounted at one end to be movable with respect to said shaft to permit said roller to move into and out of engagement with said T-slot. 
     
     
       23. The apparatus according to claim 1, wherein said guide member comprises an arm having an arcuate collar at one end adapted to engage within said T-slot, said arm being resiliently mounted at the other end permitting said flange to move into and out of engagement with said T-slot. 
     
     
       24. The apparatus according to claim 1, wherein said guide member is mounted on a support fastened onto the handrail for the V groove roller, said handrail being adjustably secured in the direction of the shaft axis, and including a mechanism capable of being reached by hand from the side of the shaft which carries the spinning turbine. 
     
     
       25. The apparatus according to claim 24, wherein said support comprises two parts, one of which is fastened unto the handrail, the other of which journals said guide member and is radially movable relative to the shaft and includes spring means interposed between said parts to bias said guide member in the direction towards the shaft.
